I wouldn't mind moving a few more copies out of this stack of 100 freshly printed books! So I'm knocking $3 off and it's shipped free in the US ($3 off international shipping). http://www.classiccomputing.com/CC/HB_Book.html Best, David Greelish, Computer Historian - Author, "The Complete Historically Brewed" - Founder, Atlanta Historical Computing Society - "Classic Computing Show" podcast - "Stan Veit's History of the Personal Computer" audiobook podcast - "Retro Computing Roundtable" podcast ClassicComputing.com | atlhcs.org

Microvax II won't boot, hardware error?

Even though early versions of VMS do not enforce licensing through the LMF, it's still required. Media can be borrowed. HP doesn't care where you get it, but asks that it not be posted for public download.

Esperanto as natural language [was RE: Learning simplified versions]

by RichA＠vulcan.com

From: Fred Cisin Sent: Thursday, May 23, 2013 1:19 PM > Should we define Esperanto as a "living human language"? That is a question that has arisen in the context of creole studies and the study of linguistic universals in linguistics. Esperanto as defined by Zamenhof violates several apparent universals of human language, and speakers have smoothed out some of those rough edges. In addition, there are reports of native speakers of Esperanto, defined as children for whom it is the first language, learned in environments in which only Esperanto was spoken. These reports have been questioned, as one might imagine, but I personally have not followed up on them as they fall outside my personal interests. So: If there are children who speak it natively, then the answer to Fred's question is certainly "yes". Given the very large community for whom it is a useful second language, with literature as well, then the answer is "yes, probably". If it were restricted (as it is not) to a minimal vocabulary with no potential for growth, then the answer would be "certainly not". I'm of the "yes, probably" camp most of the time.

TU58 tape issues

by blstuart＠bellsouth.net

So I decided to write a TU58 emulator for my 6809 SBC to serve "tapes" >from an SD card. So far, I've only implemented a first version of the read side. It seems to work on an XXDP image I found online. However, when I try to boot an RT-11 tape image, I get: @1000G?BOOT-W-Error reading handler ?BOOT-W-Error reading handler ... ?BOOT-W-Error reading handler RT-11SJ V04.00A ?BOOT-W-Invalid or missing TT.SYS ?KMON-U-Overlay read error . .SHOW ?KMON-U-Overlay read error Any ideas on what might be causing this? I've dug up the old rtpip code and gotten it partially working in a more current environment, and it seems to be happy with the tape images I have. I've had this happen on two tape images. Also the original tapes from which these images were made are ones that I've booted from (after I made the tape images), albeit over 20 years ago. So it looks like either something strange in my tape images or something in my emulator that works to load the secondary boot, but fails for loading some other parts of the tape. BLS

S100, but not S100

by dgriffi＠cs.csubak.edu

I have some boards with gold fingers that match S100, but are obviously not. For one, they're dated to 1973 and from Intel. Also, they're two inches narrower and 1.5 inches taller than an S100 board. What are they? -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

Old UNIX Systems

by healyzh＠aracnet.com

I've been working on getting shelving installed in our Garage, and as a result, I've been digging back to some systems that have been buried. Right now I'm moving a bunch of Sun hardware and it hit me. What good are old UNIX systems? I'm curious, what are people using things like Sparc 2's through 20's for? Or even Ultra 60's and older? Part of the problem I'm looking at is that you can get something like a Raspberry Pi that will cost a fraction of what a Sun system costs to run. I won't ask this about my two SGI O2's, as they're artwork. BTW, I'll be honest, I'm actually using two Sparc 20's right now. Each one sits on top of two Record Crates, and acts as a speaker stand. They've filled that role for several years. Somehow though, furniture and artworks really aren't the uses I'm looking for. :-) Zane -- | Zane H.

Another original Apple I sells for an insane amount

by tothwolf＠concentric.net

Vintage Apple-1 Sells for Record $671,400 http://bits.blogs.nytimes.com/2013/05/25/vintage-apple-1-sells-for-record-6… Whoever bought the thing from Mr. Hatfield earlier this year really should be ashamed of himself. I for one hope someone out there could at least send Mr. Hatfield one of the Apple I replicas.

Spec of Motorola 7339 Transistor

by robert.jarratt＠ntlworld.com

I am trying to find out some information about this transistor from my ASR33 Teletype. Ideally a datasheet to tell me what kind of transistor it is, and even better any information on whether it has a modern equivalent. This page: http://www.diyaudio.com/forums/parts/167680-vintage-transistors-6.html suggests it might be a 2N176, but I am not sure. Anyone have any information, old datasheets or anything else that may help? Thanks Rob

pdp11/93 mod

Does anyone have information regarding modifying a pdp11/93 cpu to run at 20Mhz? It's been mentioned on a couple of web pages, but I can't seem to find details.
